I had always practiced (and been taught) to keep the thumb outside the fingers, but it sure works well for Scott to let the thumb go under the index finger and touch the middle finger at times. I may have to give this some practice time and see if it works for me.
Scott (not pictured) has adapted his technique to the type of thumb shape and joint movement he has(*
). His thumb is relatively straight and is more folded into the palm from the big joint (third from the tip, i.e. equivalent to the knuckle joint for other fingers). Contrast with Pepe Romero's thumb (pictured) which seems longer, is not folded into the palm from the third joint, and has a significant curve away in its last phalange.
Many other guitarists , like Ana Vidovic (pictured below), have a pronounced natural 'kink' at their second thumb joint which also helps them keep their thumb away from the other fingers when playing.
The posture you have been taught may or may not suite your anatomy. This is an example of advice given (and enforced - by the way it is presented as absolute rule) which does not get to the reason or principles behind why that particular posture suits (some) guitarists - and thus can be detrimental to those whom it does not suit. Do examine your thumb and hand anatomy and see what works for you, and don't hesitate to change your current posture if needed.
My own thumb is much more similar to Scott's than to Pepe's or to Ana's (definitely no 'kink' at the second joint) so my tremolo setup is close to Scott's as a consequence.
) These are not the only factors. The thumb nail shape (in both directions), the angle it strikes the string, the 3D shape of the thumb itself under the nail all matter when finding the best posture, given your anatomy, which produces your preferred tone.
